Description:
Provide an API to allow the processing of JSR 175 annotations (metadata); this will require modeling elements of the Java(TM)
programming language as well as processing-specific functionality.

2.20 What is the URL of the Issue Tracker that the public can read, and how does the public log issues in the Issue Tracker?

2.21 Please provide the location of the publicly accessible document archive you have created for the Expert Group.

Since JSR 269 is in maintenance, there is no expert group.

2.18 Please provide a description of the business terms for the Specification, RI and TCK that will apply when this JSR is final.

Sun will license the RI binary for this JSR free of charge.

This JSR will be included in the Java SE 6 platform release. The JSR TCK will thus be licensed as part of the Java SE 6 TCK under the terms described in the JSR-270 business terms.

Sun will license the standalone TCK for this JSR for a flat fee of $50 K. In addition, Sun will make the standalone TCK available for no charge to Java SE TCK licensees, qualified individuals and not for profit organizations.

2.16 Please describe how the RI and TCK will de delivered, i.e. as part of a profile or platform edition, or stand-alone, or both. Include version information for the profile or platform in your answer.

We plan to include the RI and TCK as part of Java SE 6 as well as making the TCK available standalone.

2.1 Please describe the proposed Specification:

J2SE 1.5 added a new Java language mechanism "annotations" that allows annotation types to be used to annotate classes, fields, and methods. These annotations are typically processed either by build-time tools or by run-time libraries to achieve new semantic effects. In order to support annotation processing at build-time, this JSR will define APIs to allow annotation processors to be created using a standard pluggable API. This will simplify the task of creating annotation processors and will also allow automation of the discovery of appropriate annotation processors for a given source file.

The specification will include at least two sections, a section of API modeling the Java programming language and a distinct section for declaring annotation processors and controlling how they are run. Since annotations are placed on program elements, an annotation processing framework needs to reflect program structure. Annotation processors will be able to specify what annotations they process and multiple processors will be able to run cooperatively.

The processors and program structure api can be accessed at build-time; i.e. this functionality supplements core reflection support for reading annotations.

2.3 The Executive Committees would like to ensure JSR submitters think about how their proposed technology relates to all of the Java platform editions. Please provide details here for which platform editions are being targeted by this JSR, and how this JSR has considered the relationship with the other platform editions.

Just as JSR 175 was delivered in J2SE with extensive expected use by J2EE, this JSR is being submitted to the J2SE EC although we expect the functionality in this JSR to be heavily used by J2EE.

2.4 Should this JSR be voted on by both Executive Committees?

No

2.5 What need of the Java community will be addressed by the proposed specification?

2.6 Why isn't this need met by existing specifications?

A standardized build-time annotation processing mechanism was not included in JDK5 coincident with shipping JSR175. The core reflection support for reading annotations does not allow annotations to be read from source code (or the reading of source-only annotations). The javadoc API does not directly support running multiple pluggable modules based on what annotations are present.

2.7 Please give a short description of the underlying technology or technologies:

In order to realize the full benefits of annotations, a standardized mechanism is necessary to process them in contexts other than a running jvm. Since annotations are added to declarations (classes, methods, fields, etc.), the API needs to include a model of program structure. Additionally, the processors for different annotations should be able to work cooperatively and the set of processors that are run should be able to depend on what annotations are present in the code being processed.

2.8 Is there a proposed package name for the API Specification? (i.e., javapi.something, org.something, etc.)

All the API elements are expected to reside in the javax namespace; the language modeling portions of the API might be called javax.mirror.declaration, javax.mirror.type, etc. while the processing related portions of the API might be called javax.annotation.processing.

2.9 Does the proposed specification have any dependencies on specific operating systems, CPUs, or I/O devices that you know of?

No

2.10 Are there any security issues that cannot be addressed by the current security model?

None known.

2.11 Are there any internationalization or localization issues?

No i18n or l10n issue beyond localizing messages in the implementation.

2.12 Are there any existing specifications that might be rendered obsolete, deprecated, or in need of revision as a result of this work?

The intent is to supersede the com.sun.mirror.* APIs and the apt tool shipped as part of Sun's JDK 5.

2.13 Please describe the anticipated schedule for the development of this
specification.

The intention is to deliver this JSR as part of the Mustang umbrella JSR. Early review would occur in May 2005, Public Preview in October 2005, and Proposed Final Draft in February 2006.

2.14 Please describe the anticipated working model for the Expert Group working on developing this
specification.

A mailing list is intended to be the primary communication mechanism among members of the expert group. Conference calls may be used on an as-needed basis.

2.15 It is important to the success of the community and each JSR that the work of the Expert Group be handled in a manner which provides the community and the public with insight into the work the Expert Group is doing, and the decisions that the Expert Group has made. The Executive Committees would like to ensure Spec Leads understand the value of this transparency and ask that each JSR have an operating plan in place for how their JSR will address the involvement of the community and the public. Please provide your plan here, and refer to the Spec Lead Guide for a more detailed description and a set of example questions you may wish to answer in your plan.

We anticipate providing draft specs every two to three months after the first draft is released until the Proposed Final Draft. A JSR interest mailing list will be established so interested parties can be informed of issues under discussion.

2.16 Please describe how the RI and TCK will de delivered, i.e. as part of a profile or platform edition, or stand-alone, or both. Include version information for the profile or platform in your answer.

This JSR and its RI and TCK are intended to be part of the Mustang RI and TCK, respectively.

2.17 Please state the rationale if previous versions are available stand-alone and you are now proposing in 2.13 to only deliver RI and TCK as part of a profile or platform edition (See sections 1.1.5 and 1.1.6 of the JCP 2 document).

Not applicable.

2.18 Please provide a description of the business terms for the Specification, RI and TCK that will apply when this JSR is final.

The RI and TCK will be delivered and licensed as part of the RI and TCK for Mustang.
